Reconstitute the lyophilized powder with deionized water (or equivalent) to an antibody concentration of 0.5 mg/mL.
His-tag Antibody, pAb, Rabbit recognizes His tagged proteins in transfected or transformed cells. Short-sequence epitope tags are common in the study of protein expression in several different expression systems. In particular, the His tag on the expressed recombinant proteins allows for efficient coupling to Ni2+ affinity resins and purification by single step chromatography.
Upon reconstitution, it can be stored for 2-3 weeks at 2-8 °C or for up to 12 months at -20 °C or below.
The 6x His tag is a synthetic oligo peptide consisting of 6 consecutive histidine residues (HHHHHH). The His tag is commonly expressed as a tag at either N-or C-terminal regions of recombinant proteins to allow isolation or purification by immobilized metal affinity chromatography. Epitope tagging is a technique in which a known epitope is fused to a recombinant protein using genetic engineering. By choosing a particular epitope and recombinant protein combination, epitope tagging makes it possible to detect proteins for which no antibody is available. His epitope tagged proteins that contain a stretch of histidine residues at the carboxyl or amino terminus are used for purification of recombinant proteins by means of metal chelate chromatography due to metal binding properties of histidine clusters on His tagged proteins. For example, the affinity of the histidine-tag motif to Ni2+ by chelation is strong and selective enough to enable purification of the protein to homogeneity by affinity chromatography on a Ni2+-NTA adsorbent. His tag-specific antibodies are used to facilitate detection or coimmunopreciptation of tagged proteins.
